Warm Sounding Speakers

Dorgay's review is here.

The current Bose Series VI has been around for 25 years. I wonder how good the design could be today with the better full range 4" drivers available today, say with neodymium magnets, composite cones, cast frames, phase plugs, and high excursion surrounds, plus an active crossover with higher quality parts.

Then put them at the proper height on solid, rigid stands such as Dorgay used.

It *does* have some things going for it, such as crossoverless design and uniform power response.

Dsper, if you haven't already done so, I suggest doing a Google search on past online reviews that have been posted on the Krell 300si to see if any of them talk about specific speakers that mate well from the perspective of warmth.

Warm sound will almost always require tubes, but I love all the Sonus Faber speakers I have owned (which is about 4 different models over the years). Still currently using the Sonus Faber Cremona. Not sure how it would sound with your Krell.

Johnnyb53, Bose 901s are continuously being revised. The most recent revision was in 2010. They use an acoustic matrix enclosure and helically-wound aluminum voice coils. You can run them on 10-450 watts. I would love to try 901s, but they will not work in my room. However, I did experiment with Bose 301s and I was very impressed especially for the price. Like Dorgay's description of the 901, the 301 also suffers from "sin of omission", but it does so many things right it boggles the mind that the speaker retails for only $328. If you go too cheap on electronics and cables the 301 will sound dull and lifeless. It really needs to be treated like any other speaker in terms of associated equipment and room placement. I used the 301 on very heavy four pillar stands, sand filled and spiked to the floor and Blu-Tack.
Associated equipment consisted of a vintage Yamaha receiver, Quicksilver 90 watt monos, Quicksilver Full Function preamp, Tandberg 150 watt stereo amp with matching preamp and Audio Research CD3 MKII and Kinergetics KCD-40 CD players. I also experimented with several inexpensive CD/DVD players, but I was not satisfied with the results. My friend Mike is also experimenting with 301s only he will not admit it to anyone lol.

The Krell Resolution II is a really great sounding speaker voiced on the "warm" side and would mate well with your Krell integrated. I traded my pair in to Audio Video Logic - where I believe they are still available for sale. I took very good care of them.
